Encinitas, California--(Newsfile Corp. - March 25, 2025) - Kiora Pharmaceuticals, Inc. (NASDAQ: KPRX) ("Kiora" or the "Company") today announced its 2024 financial results and provided an update on its pipeline of therapeutics for the treatment of retinal diseases.

Key fourth quarter and 2025 year-to-date corporate highlights include:

  • Received approval to initiate KLARITY, a Phase 2 trial of KIO-104 for the treatment retinal inflammation.

  • Received approval to initiate ABACUS-2, a Phase 2 study of KIO-301 in retinitis pigmentosa (RP) in collaboration with Théa Open Innovation (Laboratoires Théa).

  • Received $3.3 million in reimbursed R&D expenses in 2024 from Laboratoires Théa for development activities related to KIO-301, of which $2.9 million was recognized in offsetting collaboration credits.

  • Ended the year with $26.8 million in cash, cash equivalents and short-term investments plus $0.9 million in collaboration and tax receivables.

  • Expected runway into 2027, excluding any potential partnership milestones, beyond the data readouts from KLARITY and ABACUS-2 expected in 2026.

"In 2024, our team undertook extensive preparations to initiate two Phase 2 clinical trials that have received approval and will begin enrolling patients in the coming months," said Brian M. Strem, Ph.D., President & Chief Executive Officer of Kiora. "The KLARITY study will evaluate KIO-104 in patients with retinal inflammation and ABACUS-2 will evaluate KIO-301 in patients with advanced retinitis pigmentosa. Getting these studies underway are our two greatest priorities for this year with data expected from both in 2026."

"For KIO-301, we received approval in the fourth quarter to initiate ABACUS-2, a 36-patient, multi-center, double-masked, randomized, controlled, multi-dose study in patients with ultra-low vision or no light perception due to retinitis pigmentosa. Dosing of the first patient will begin this year following the completion of an ongoing clinical endpoint validation study. We anticipate that the patients we've enrolled already for this validation work meet enrollment criteria and will participate in ABACUS-2.

"Following interactions with the FDA and European regulators, retinal specialists, and patient advocacy groups, it's clear that demonstrating improvement in functional vision is essential for marketing authorization as well as reimbursement. This underscores the importance of the investment in time that we are making to refine the clinical endpoints that can measure clinically meaningful improvement in patients with no vision or bare light perception. This will increase our confidence in the data we generate from ABACUS-2 as this same endpoint would likely serve as the primary endpoint for a Phase 3 registration study.
